Induction of localized rains is a technology that can be used to increase the occurrence of rains in many regions contributing to:

Water Supply

ModClima is an expert in projects focused on water supply. Since 2001, we have executed more than 600 rains in Sao Paulo for SABESP, helping the largest water supply company in Brazil and in Latin America secure the water supply of 20 million people.

The application of the technology for water supply projects can only be successfully applied on medium and long term projects. Working on a continuous basis, taking advantage of every opportunity to induce precipitation over the contribution area of the reservoirs, we can increase the moisture stored in the soil, recharge the groundwater and underground network, and maximize the water from natural and induced rains that run straight to the water reservoir.

When the soil is too dry, the rains that do not fall directly on the water reservoir quickly evaporate and return to the atmosphere, and they do not contribute to increase the level in the reservoir. By keeping the soil in and around the basin as saturated as possible, we can help increase the contribution of natural rains to refill the reservoir.

Areas that feed into rivers and reservoirs can also benefit from the artificially induced rain. Our rains contribute to the maintenance of native vegetation around these areas, reduce the chances of outbreaks of fire, and preserve these areas of extreme importance.


For the agriculture sector, we work with customized projects to mitigate and adapt to the effects of droughts, and meet the needs of farmers and/or cooperatives. On average we work with a minimum area of 30,000 hectares.


Key variable in our projects:

  • Number of seeding flight hours
  • Total area of the project
  • Water need of the crop/plant
  • Historical climatology in the region
  • Current status of culture (water stress)


ModClima projects can increase the volume of water for hydroelectric energy through increased rainfall over upstream areas of rivers. By seeding clouds with pure water (ModClima does not use the term bombardment of clouds), it is possible to secure water levels in reservoirs and increased production of electricity in a clean way.

Biodiversity Preservation

Our localized rains can help make forests healthier and therefore more suitable for preservation of life and biodiversity. Our rains can also be induced in areas suffering from water shortages or at risk of desertification. In both cases the technology presents a new tool to minimize the impact of droughts and assist biodiversity conservation.

Wild Fires Prevention

Our technology of localized rain induction can be applied in forest conservation projects, reducing the risk of forest fires. Focusing on prevention, we can induce rains in national parks during the rainy season, optimizing water retention in the soil and native vegetation and helping the region prepare for the drought period. At the end of the dry season, when vegetation and soil are at its driest, we can take advantage of the first clouds in the early rainy season to anticipate rains and reduce the period of water stress.

By lowering the number of fire outbreaks, we can help fight global warming by preventing an enormous amount of CO2 from being released into the atmosphere.


Eucalyptus and sugar cane productivity are directly related to the volume of water available, and among all cultures this relationship is more linear for the eucalyptus forest. Thus, the application of our technology in long-term projects can generate many benefits for the forest sector:

  • Easy application on large areas;
  • Reduction of tree mortality from water stress during the first month;
  • Application throughout the year, acting to "stretch" the end of the rainy season and "anticipate" the beginning of the rainy season, decreasing the period of water stress on the target region;
  • Reduction of the risk of forest fires;
  • Possibility of direct (mm rain) and indirect (girth) measurements during the course of the project;
  • Possibility to separate the project into two areas (A – with seeding, B – no seeding) to study the effectiveness of the technology;
  • Better use of farmland that already have environmental license;
  • Increased growth rate will reduce the amount of time needed for tree to achieve cut size;
  • Innovation creating competitive advantage.
